Looking for something that's smaller diameter than those little bottles from home depot that are around $3 each.

Is there such a beast ?

Looking for something that's around 2" or less in diameter.

How small ID barrel can you go safely using a 3" chamber ( ABS material ) .

Can I go as small as 1/2" ID or even smaller ?

Using a spray and pray propane battle.


Right now I'm using a 2" chamber and going down to a 1/2 " with no issues using propane.


Thanks

Those electonic igniters are extremely nifty, but it would be great if they weren't completely potted so that you could remove the battery holder, casing, etc, and hide it away in a handle or project box... To relocate the button would be simple, and you could choose whatever momentary button you w...

what is the wally world ignitor you were talking about? I may pick one up today if you tel me what im looking for. If you look at the video, it's the first thing in it. It takes a single AA battery and I have yet to run that battery down. Probably have zapped it 4K times by now, and it's still goin...

Ya I know, I just can't make a video without having some some kind of music. Everything in the pic is just ABS pipe and fittings. I molded everything you see using Duracoat, and sprayed it with the Krylon Camo Ultra flat. I would have loved to have molded the whole thing, but I wanted to be able to ...

Here is a little 2.20 minute video I put together . I had not built anything related for the past 15 yrs, but as soon as I found out about the Cam and groove couplers I just had to build another. Also finding out about the $17 WalMart Electric ignitors that takes the AA, batteries helped as well. Th...

This is what I would personally use. You have your choice between two differant thickness of sidewall, but either will get you 2.625" ID. Get an aluminum cap that's the OD of the barrel and have the center threaded out to your fitting, then have it welded on. http://www.onlinemetals.com/merchant.cfm...

I am going to be running 200 PSI max in my little toy , but wanted a PSI gauge that would go slightly above that so I can tell if I ever go over. I would like to see incriments of 5 psi. 1-1.5" Diameter max. I went to McMaster and I am just overwelmed on what to get, there are just to may options. C...

Thanks that was exactly what I needed.

I'm not familiar with "AN" threads. Did you mean UNF-12or UNC-12? AN stands for Army Navy. If you look at Nitrus oxide connectors on race cars it's what they use to hold 1000PSI or more. Usually they are anadized Aluminum, either Black, Blue or Red. The connectors are just very flexible compared to...

I know exactly what you are trying to do because I have been after the same thing . I can't answer your question , but I can say that a 3/4" QEV by Fastenels will fit inside of a 2.25" ID tube and that's with the 90 degree elbo that has to go on the top that goes to your air chamber. I just had to b...

Been doing a little research and realize I can use AN-12 threads over and over again and they never wear out when the 3/4" NPT are only good a few times then you have to toss them. I also am told I don't have to use teflon tape when using the AN-12 threads. Pro's and cons ? My project will only see ...

Go for it then. Still, i suspect that drawing enough power from a 9V battery to get a piece of wire to go incandescent is going to kill the battery pretty darn quick. I would suspect the battery to go dead within tens of seconds. Figure each firing is at least a second or two of power and ... Inter...

What voltage is that and what's the gauge of the 8 strands ?

Seems to light really slow, that's why I'm asking.

IIt would still be a smaller set up than 95% of any other ignitions mentioned on this forum. Only if you omit 95% of the guns which use piezos. A bbq piezo is simpler, and in the long run cheaper, than anything else. 9v battery is a couple bucks battery clip $1 suitable switch a buck or two somethi...
